A golfer with several swing flaws will never be consistent for 18 holes of golf.
NY....In most instances I'd agree with the above. But there are anomolies. I think H Penick told Ben Crenshaw and Tom Kite to not be afraid of the guy with the good swing and the bad grip.......and to not fear the guy with the good grip and the bad swing. The one they needed to watch out for was the guy with the bad grip AND the bad swing.
If you can repeat it.......it's lethal.
Sounds like your bud's an anomoly, as well.
